SAMUEL F. ARIBUUKLE, or -mnranaroms, INDIANA.

ELECTRIC-LIGHTING sYs'rnivr.

' To all whom it may concern:

Be it known that I, SAMUEL F. ARBUCKLE, a citizen of the United States, and a resident of Indianapolis, county of Marion, and

5 State of Indiana, have invented a certain new and useful Electric-Lighting System; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying parts. I v

The object of this invention is the provision of a better electric lighting system for automobiles, and the like than heretofore devised.-,, 4

One feature of the invention consists in providing means whereby the chauffeur of an automobile can readily dim a lamp or light, I say, the right-hand headlight and leave the left-hand headlight at full strength or any strength desired. This arrangement protects approaching drivers ofvehicles i from the. glare of the left-hand head light and yet leaves the right-hand light going at full strength to illuminate the right-hand edge of the roadway .and thus enable the chauffeur to see how to drive his automobile continues at full force to illuminate the right-hand'side of the roadway and does not blind with its glare any persons approaching on the other side of the roadway.- The left-hand light which causes the dangerous glare is dimmed and, therefore, with the one device both objects areaccomplished, namely, the protectioii of approaching persons from the glareof the lamp and also the illumina- EO-tion of the right-hand side of the roadway to protect the automobile. Also the dim left-hand light is sufficiently strong to serve as a signal onwarning to approaching automobiles and enable them to see how close I they are' coming to the automobile equipped wlth' appli'cants invention. Where the glare drawings, in which like, letters refer to like without the taillight being on.

With this improvement the right-hand light Specification of Letters Patent. I Patented Apr, 17, 1917,, Application filed January 24,1916; Serial No. 74,058.

is not reduced neither automobile chauffeur can prevent collision as neither can'see either automobile or the exact position of its lefthand side in the roadway and the same thing is true when the headlight is turned out.

in providing a means for dimming or brightening or shutting off either' headlight or both, as desired, and also'for gradually dimming both headlights until they are entirely shut ofi'.

Another feature of the invention consists in providing such controlling means or signal, so-th'at whenever the tail light is shut off, the headlight will be shut ofi. This is in order that the tail lightwould always be on necessarily when any other lights are on so thafl at night the car cannotbe driven Also the arrangementis such that the tail lights cannot be turned off without turning ofi all of the other lights, particularly the headlights.

Another feature of the invention consists in providing a single switch for doing the following workrWhen the switch is in its first position, the tail light and all other lights on the same circuit as the tail light, will be turned on; when the, switch is in the second position, said lights will be left on and the headlights will be turned on with full brilliancy; when the switch is in its third position, one of the head-lights will ,be

dimmed to any degree desired and the other lights be left on unchanged except that the other headlight may be also slightly dimmed, if desired, without any of the other lights besides the headlights being dimmed; when inits fourth position, all lights will be brilliant,,although the headlights will be slightly dimmed, and further advance move- Another feature of the invention consists ment of the switch will gradually dim the headlights, but leave the other lights brilliant, the headlights being dimmedto a minimum; when the switch as gradually at its fifth position, there is a 'snap signal indicating that the head'lights are dimmedto "their minimum; and when the switch is .muved to thesixth positionfall'lights are off. If the switch be operated backward, the

same efiects will be produced, but in reverse v order.

Another feature of the invention consists in arranging the switch so that it will be locked against operation unless itjis unlocked by the insertion of a key the of its positions, as above defined, and it canin combining a switch for controlling the lighting circuit with a switch or means for controlling the ignition circuit arrangedso that thelighting switch cannot be operated until the ignition switch key is inserted and operated. In other words, means is provided for locking the lighting switch in any not be unlocked except by the use and operation of the ignition switch. This insures the closing of the ignition circuit at all times when the lighting switch is operated and prevents the actuation of the lighting switch excepting when the ignition circuit is closed. ,On the other hand, the locking key can be removed and the ignition circuit broken when the lighting switch is in any one of its positions so that the lights may continue although the ignition circuit is broken.

The full nature of the invention will be understood from the accompanying drawings and the" following description and.

claims:

Fig. 17 is a similar diagram partly shown when both headli hts are dim. Fig. 18 is a similar diagram w en a "all of the lights are off. Fig. 19 1s a section on the-line 19- -19 of Fig. 6, showing inside e' 'l' av a tiDn of the disk. ,;Fig. 20 shows a porllidtgof 6;. with the switch locked.

iii-this device, as shown for the purpose ofj illustrating thegeneral nature of the 111- vention, there is 'a circular face plate 10 adapted to be secured to some part of an auit to receive a collar 11 extending inward from a base 12 of a finger piece 13. Said fino ger-piece also has anindicator 14 integral therewith. The base 12 is. turned 01' rotated by the finger piece and the index refers to' words on the face plate which state the differentv positions of the switch. 5 On the inside of the face plate, 10 there is a disk 15 made of insulating material which is secured by screws 16 to the base of the finger piece, as shown in Figs. 2 and 6. Therefore, the disk 15 rotates with the finger piece and it has a central square opening through .which a square post or stem 20 extends, so that when the finger piece is turned, said disk 15 will turn said post or stem. Said post is made of. metal or other 35 conducting material and extends through" and turns three diametrically extending spring plates 21, 22 and 23. Said stem extends through and turns in an opening or hole through the switch base 25 which is made of insulating material and has a cylindrical extension 26 secured to the face plate 10 and made of insulating material. It is "through the ring 28, plate 21 and -stem 20 and is conducted to plate 23, as hereafter explained. The plates 22 and 23 are insulated from each other by-a rubber disk 29 and plate 22 is insulated from the post 25 by the disk 29.

The rear surface of the switch base 25 is cylindrically stepped and has secured to it an inner metal ring 30, a second metal ring 31 of greater diameter, and a third metal a ring 32 of still greater diameter. One end -of the spring metal plate 23 bears upon the outer ring 32 and the other end bears and travels upon a resistance coil 33, segmental in form, as appears clearly in Figs. 4 and 14. Said resistance coil lies in a recess 34 in the switch base and is secured at intervals to said switch base. The gap between the ends of said resistance coil 33 is filled by a plate 35 of non-conducting material, segmental in form and rigidly secured in said recess 34. to the switch base and arranged so that its rear edge will be flush and in alineinent with the rear edge of the resistance coil 33 so that the longer end of the spring plate 23 13o can travel and not contact with said coil 33 and plate 35 when the finger piece 13 and stem are turned in either direction. The spring plate 23 is held on the stem 20 by a pin 36. v

The rings 30, 31 andf32 are formed, as

shown in Fig. 4. The inner ring 1s broken at two points to make the short segment 130 and the two parts of said ring are separated by non-conducting material. The ring 31 is likewise formed of two parts, one being a short segment 131 and said short segment 131 in; ring 31 isdiametrically 0pposite the short segment 130 of .ring; 30. Therefore, the spring plate 22 will bridge either. the two longer portions of the rings 30 and 31, or the two shorter. segments 130 and 131. The outer ring 32. is likewise formed of a longer portion and a shorter segment 132. The segment 132 need not be of metal necessarily, and it has no electrical connection of any kind andwhen the spring plate 23 is in contact with that small seg ment 132, the lines are all cut out.

The electrical connections with the rings 28, 30, 31 and 32 are constructed as follows: The current leaves. the battery'40yshown in the diagram in Fig. 13, and passes over the line 41 to a bind'screw 42, shown in Fig. 7, and metal plate 43 secured to the switch base 25 by a screw 44- through", which the current passes to the ring 28. The switch base .25 issegmentally cut out at 145, as indicated in Fig. 6, for the purpose of connecting these electrical connections with the rings. The current passes from the ring 28 through the stem 20 and through plate 23"' to ring 32 and therefrom through theelectrical, connections shown in Fig. 9. '40' From said ring-the current passes through a screw 45, plate 46, screw 47 and wireor line 48 and goes to the tail lamp 50 and therefrom to the ground'at 51,- as indicated in Fig. 13. This tail-light, therefore, 'will always be lighted during the turning move ment of the switch until the short end ofthe spring plate 23' comesupon the short segment 132 of the outer ring 32, shown in. Fig. 4, and heretofore described as being insulated and having no electrical connec tion. When it is in that position, the tail light will be out. When the device is in idleposition and alllights are ,ofi, the

"short end of the spring. plate 23 is located on said short Fig. 18.

As soon as the switch is turned so as to move said plate ,23 onto'the main part of,

segmentv 132, as indicated in ring 32, then the tail light will be on and" that constitutes what may be termed the first position of .the lightingswitch. The fact that it reaches the first position is made known by a click or signal caused by a rib 51 on the metal plate 21 entering a .notch 52 in the ring 2 8. The rib and notch referring to Fi are beveled'sothat it will not interfere with further turning movement of the metal plate 21. Also such position is indicated by the pointer 14 pointing toward the words Tail light on the face plate 10.

The next movement to the right of the finger piece until said rib on the metal strip.

21 enters another notch 52 in the ring 28,

brings the light switch into the second potrical connection with such end of the resistance coilis shown in Fig. 8. It consists-of a wire. 152 or one end of the coil connected with a plate or binding'post 53 and the current passes therefrom through a screw 54 to line 55, see Fig. 13, and then to the right-hand head light 56 and thence to -ground at 57. The binding plate orpost 53 is held in place by a screw 157 so as to be connected by a screw 58 with the largeseg-- ment of-the inner ring 30. A portion of the current passes through the binding plate or post53 into, the larger segment of the inner ring 30 [and therefrom through the short end of the spring plate 22 to the large segment o-f,the ring 31 and from that ring,

as shown in Fig. 72, the current passes.

through the screw '158, binding plate 59, screw 60 and line-61, as seen in Fig. 13, to the -left-hand headlight 62 and thence to ground 63. 1Theref0re, both'headlights will be turned on with full and equal brilliancy.

When in thisposition the pointer 14 points toward the word On, as indicated bydiagran in Fig. '15.

When the finger piece or switch is. given a further movement until the rib 51 on the plate 31 enters another notch 52. in the ring v 28, the pointef 14 will point toward the words Left dim on the plate 10. That means that the left-handheadlight 62 is dimmed while the right-hand headlight 56 is still brilliant and the tail light is still on, as indicatedby diagram in Fig. 16. By g. 16 and the resistance coil therein, it will be seen that the current'going. to the left or dimmed headlight extends from the point where the plate 23 engages saidcoil to the left entirely to the end of the coil, while the resistance in the circuit going to the right-hand or more the coil'lying between the plate 23 and the right-hand end of the coil. Therefore, while there is some resistance in the circuits to both lamps, there is a very great difference in the amount of resistance.

The mechanism whereby the above result is accomplished is as follows: The. circuit for the right-hand or more brilliant light is the same as heretofore excepting. that brilliant headlight is only that portion of there is some of the resistance coil now in the circuit in View of the movement of the plate 23 for a slight distance along said coil. The current for the dimmed headlight travels as follows: The current from the plate 23 travels throughthe longer or left-hand portion of the resistance coil and through the connection to the short segment or portion 131 of the ring 31. Thence it goes to the plate 22 which bridges said middle ring 31 and thence it passesthrough screw 158, plate 59, screw 60 and line .61

to the left or dimmed light 62.

Soon after the switch is started from the third position, the spring plate 22 moves away from the portions 130 and-131 of the inner and middle rings 30 and 31 upon the longer segments or portions of said rings. The current which comes in over the spring plate 23 now travels to the right through the resistance coil to its right-hand end and then a part of it out through line 55 to the right-hand headlight and a part of it through the connection 58, see Figs. 8 and 16, to the inner ring 30 and since it is bridged with the middle ring 31, the current passes to said middle ring and out through line 61 to the other headlight. This will give both headlights equal brilliancy, but obviously as the switch is operated further and the spring plate 23 is'caused to travel to the left on the resistance coil, as'

indicated in Fig. 16, the amount of resistance in the circuits to the two headlights will be gradually increased and the power of said lightsv correspondingly gradually diminished until the end of the resistance coil is reached, when the light in said headlights will be reduced to the minimum. During this part of the-operation, the pointer 14 passes over the section of the plate marked, Variable, and the power of the headlights is reduced when the switch is turned until it is stopped in the fourth position by another notch 52 in the ring 28. Then the pointer 14 points toward the portion of the plate 10 marked Signal lights, by which is meant the two dimmed headlights. However, the tail light isstill on.

7 Further turning of the switch will bring it to the off position when all lights will be turned'ofl. This is the fifth position and at that-time the pointer 14 will point toward the word fOff on the plate 10. The off position of the parts has already been described Fig. 17.

72, as shown in Fig. 13.

and is indicated by diagram in' The i'gnition circuit leads from this device througha wire to the spark plugs of the engine 71 and thence to the ground at I The wire 70 is connected with a plate 74 by a'screw 75, as shown in Figs. 13 and 6. The plate 74 is secured to theswitch plate 25 by a screw 76. A metal plate or conductor 77 is connect'ed with the plate 74 and extends in the chamber 27 almost to the stem 20, as seen in Fig. 6, where it is adapted to be engaged by a spring metal plate or conductor 78 when its free end is depressed by the'insertion of the locking key 80 and thus the ignitition circuit be closed. Suchignition circuit leads from the ring 28 which is shown to be electrically connected with the plate 78 by a metal plate 81. These two plates 78 and 81 are secured togetherand clamped and held between the switch base 25 and the cylindrical member 26, as seen in Fig. 6, but the connection between the parts 27 and 78 is not limited to the details shown.

Therefore, the current for both the lighting and ignition circuits comes from the same bat-- tery through line 4l and connection 43 and metal plate or strip, 21 and ring28. These connections and conductors'are in common with both the lighting and ignition systems.

The spring plate 78 carries a pin 83 adapted, when theplate 78 is not depressed by the key 80, to project into one of the holes 84 in the stationary disk 15 which is fastened to the base plate 10, as shown in Fig. 6. That locks the lighting system from further manipulation or change until the key is inserted for unlocking the lighting switch and when the key unlocks the lighting switch so that it can be further operated, it, at the same time, turns on the ignition system.' 'When the lighting switch is locked from further operation, however, it does not meanthat the lights are all off. For there is one'of these holes for each of the positions of the lighting switch heretofore defined so that when the key is removed, the lighting switch is locked in one of said positions and if any of the lights are on when the lighting switch is in that position, said lights will continue, although the ignition system is not in operation. This renders the combination with the ignition system a very important improvement, as it enables one device to control both the lighting and ignition systems and thekey which controls the. ignition system to lock the lighting switch and to lock it with the lighting switch in operation, ifldesired; Also when theicar is standing and the ignition system is'not in operation, the device prevents anyonefrom tampering with thelights, which is an important feature. I

The details of the locking mechanism are as follows The finger piece 13 of the lighting switch has a key hole 85 extending through it, as shown in Figs. 2" and 6, the inner portion of said key hole being cylindrical and relatively enlarged, While the' outer portion is provided with shoulders 86 having a slot between them merely large enough for the insertion of the key. When the key is partially inserted in said key hole, it engages a plunger head 87 operating in the key hole andsecured to a plunger rod 88 operating in the central opening in the metal stem and having a disk 89 on its lower end adapted to engage the free end of the spring plate 78 which loosely surrounds the stem 20, When the key is pushed in to its limit, as shown in Fig. 6, it will depress the spring plate 7 8 from the position shown in Fig. 20 to that shown in Fig. 6, and bring it;into contact with. the plate 7 7 and thus close the ignition circuit. When the key is in to its limit, it is turned so that the outer wing of the key will pass under the shoulders86, whereby said shoulders will hold said key in and throughthe plunger 88 hold the plates 7 7 and 78 in circuit closing position, as shown in Fig. 6. When the key 80 I is in this position, the ignition system is in operation and the lighting switch can be turned and operated to any desired position; But as soon as the key 8O is removed, the spring plate 78 will return, moving out of engagement with the plate 77 and forcing thepin 83 into a hole 84: in the disk 15 and thus lock the lighting switch in the position in which it happens to be at that time.

It. is obvious to electricians and those skilled in the art that the details of this mechanism can bechanged in many particulars without in any wise departing from the spirit or principle of this invention and, therefore, I do not wish to be considered as limiting my invention to the details of construction shown and described, nor do I wish this invention to be limited to any particular construction or arrangement of rheostat, whether it consists of one resistance coil, or more, or some otherform off'rheostat; nor is this invention limited to use in connection with automobiles as it can be'used on steam boats and other water crafts, on trains and interurban cars and in many other situations.- i
